The present invention relates to improved means or device for fixing hermetic packing such as and more or less similar to that described in the specification of my application for a patent to the United States Patent @ffice Serial No. 645,361 of 22nd of August 1911, and is employed to tighten the rotary Valves such as and similar to those described in the specification of application for British Letters Patent filed under No. 11268 on the 11th of May 1912, the said valve or valves being arranged at the side of the cylinder or cylinders as it is shown in the drawings ofthe last mentioned application.

The object of my invention is to obtain a better accessibility into the valve, in order to facilitate the removal and replacement of the parts, without the necessity of having to dismount the valve as is necessary in connection with engines now in use.

In the accompanying drawings two torm's of carrying out my invention are .shown by Way of example. Figures 1 and 2 showing 'similar cross sections through the valves,

the section plane passing also through the axis of the cylinder. l

According to Fig. 1 the packing 1 with its spring washer 2 and a second packing 3 are rings.

The rings are fixed in the cylinders Yby means of a special key such as or similar to that described in the Belgium Patent, No. 236587. of the 17th of J une 1911 having projections for example, enacting With holes 5 in the ring. To allow of fixing the same, an f opening 6 is provided in the opposite Wall of the cylinder and is normally closed by a plug or the like 7.

Fig. 2 shows a modification in which the ring itself, which keeps the hermetic packing members, is not threaded but is simply a face ring as shown at 8 Where it Will be seen that it is quite plain andl is kept in its place by a threaded ring 9.
